The Horti Domitiae were a set of private gardens in ancient Rome, belonging to Domitia Longina, wife of the emperor Domitian. They were sited on the right bank of the river Tiber. A few years later the Mausoleum of Hadrian was built in the same area. The gardens were still known by this name in the time of Aurelian.
